    "abstract": "We consider the covariant Spectator equation with a One Boson Exchange (OBE)\nkernel, and apply it to the NN system. Relativistic effects such as retardation\nand negative-energy state components are included in that equation. We develop\na method, based on the Pad\\\u0027e method, to solve the Spectator equation without\npartial wave decomposition. The convergence of the partial wave decomposition\nseries is tested as a function of the energy. The on- and off-mass-shell\namplitudes are calculated. The NN interaction was fitted to the differential\ncross section for NN scattering, in the energy range below the pion production\nthreshold.",
